Examples
A Y- or L-shaped twig or rod, called a dowsing rod, divining rod (Latin: virgula divina or baculus divinatorius), a "vining rod" or witching rod is sometimes used during dowsing, although some dowsers use other equipment or no equipment at all.
The dowser then walks slowly over the places where he suspects the target (for example, minerals or water) may be, and the dowsing rod dips, inclines or twitches when a discovery is made.
